Help please - using ramp shader as a bump map.

Hi,

I'm working through a tutorial and my attempt is not working as it should. Basically, in the hypershade window, you create a ramp shader for the colour gradient, and then use a copy of the same ramp to bump map noise onto the tooth. This should result in straight, vertical styrations that gradually fade out.

Mine don't though - they appear to spiral somewhat, and there is an obvious seam on one side. Shouldn't it be seamless, given that it is a gradient in the V direction (starting from the bottom up, all the way around)? Also, shouldn't it be straight? It is in the tutorial video.

Here's an image.

thanks,

gubar.

Maybe it’s because you’re rendering with Maya Hardware, instead of Maya Software.

I don’t know what’s going on…… I hope someone else can help you. It could help others help you if you posted a pic of the shader network.
